Any chance that 120 hz refresh rate could cause eye strain? Noticed that if I read on my ipp 10.5 for more than about 20 minutes, my eyes get tired and I develop a headache. Reading on my ipp 9.7 was always as good as reading on my kindle.

Really shouldn't happen, no. In fact, 120Hz should feel more natural to your eyes. Hmmm. Unless of course it has to do with your eyes just being used to slower refresh rates and it's just a transitional thing

It may also be a contrast (text vs. background) issue? I had mentioned this a post a couple of days ago. Words and text just don't seem to pop out on my 10.5 ipp like they did on my 9.7. No doubt that video and pictures have more detail and better color on the 10.7, but maybe Apple did not fine tune it for readers.

If you're reading a static image/page, the refresh rate drops anyway. It's adaptive depending on what is displayed. I don't see this causing eye strain. Very strange.

If your using iBooks try using either inverted mode or the sepia page colours.

I don’t thing it’s the refresh that’s the issue for some as higher refresh is actually easier on the eyes. I think it’s the brightness levels.

I had reported the same problem a few days ago ... https://forums.macrumors.com/threads/ipad-pro-10-5-bad-text-sharpness.2051277/

In my ipp 10.5 text si not sharp as in the old IPad Air 1
All "not Apple app" (Facebook, Twitter, YouTube, etc etc) not yet update for new resolution and they simply fit and stretch into the new iPad 10.5 resolution generating blurry text.

For this i'm using Safari only....but I found the blurry text even with safari and iOS 10 and 11 in general. I'm waiting for a second ipp to compare them and verify if is a generalizated problem or is only on some device

In fact, when I switched to 120 Hz monitor, my eye fatigue reduced drastically. In case of iPad, it might be dropping to 30 Hz while reading text and that can cause eye pain.

Any place but here or there....
No ProMotion strain here. But I can relate and appreciate that Apple offers the option of reduced frame rates. I have found that using Night Shift reduces eye fatigue and strain for me. I know it is different than refresh rates, but using it has helped considerably.

Same here I noticed the same at the Apple Store after 15 hard use. Probably why I'm keeping my 9.7" no eye strain or dizziness

Think about it no one has used a 120hz Display at such close distances ever before. Even a 120hz TV or PC monitors you are a few feet back

Higher refresh rates = less eye fatigue. In fact a movie on film is 24fps and to help prevent eye strain and flicker each frame is displayed 2x for 48fps. The higher the refresh rate the closer to natural vision the image becomes. In real life the refresh rate is infinite so image the eye strain this would cause.

I thought the new iPad used the slower refresh rates with static screens like reading and only increased refresh rate when needed. Reading should use the slower rate unless you are scrolling at the same time and that would give me a headache.

A led/oled screen wouldn't need to refresh until something changed afaik.
It's just with motion that the refresh rate becomes important.
